Ultrasonic Powder Screening


RTUL’s ultrasonic powder screening machine is composed of ultrasonic vibration system and sieving machine with unique technology. RTUL’s Ultrasonic Powder screening machine is used for screening iron powder, which works well on dry materials including polymers, pigments, oxides, non-organic, organics, feed and food, etc.

With our high tech ultrasonic powder screening equipment we have transformed conventional sieving procedures. Not only can the screening process be accelerated radically (Up to 30 times) also the mesh quality and its lifetime can be increased. Also you improve your throughput and the quality of your products.

  • A significant increase in throughput volume is possible (3 - 30 times depending on material and size of particle).
  • Considerable decrease of sieve screen blinding and clogging results in a consistent throughput volume.
  • Patented ring resonators produce an even distribution of mechanical oscillations, even for larger sieving frame sizes.
  • The system has a low power consumption of approximately 60 Watts/m of screen area.
  • Low, constant operating temperature without localized heat zones.
  • Rigid, explosion-proof, waterproof, stainless steel design.
  • Long sieve life-span, will not degrade the sieve screen.
  • Short pay-back period due to incomparable cost effectiveness.
  • Mechanical cleaning or auxiliary installations can be eliminated, therefore preventing foreign particles from entering the bulk material.
  • Maintenance-free operation.
  • Option of continuous or pulse vibration with adjustable amplitude.
